ESD5431N

TECH PUBLIC · Electrostatic And Surge Protection (TVS/ESD) · DFN1006-2

ESD5431N from TECH PUBLIC, in a DFN1006-2. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 1 passive One terminal of the 1-line bidirectional TVS diode; the datasheet gives reverse working voltage 3.3 V max, breakdown 3.6 V min, and clamping voltage 9 V max at Ipp = 8 A (8/20 µs).
2 2 passive Other terminal of the 1-line bidirectional TVS diode, symmetric with pin 1 because the device is bidirectional; same ratings apply (reverse working voltage 3.3 V max, breakdown 3.6 V min).

CAD (KiCad official)

  • Symbol: ESD5431N
  • Footprint: Diode_SMD:D_SOD-882
  • 3D model: DFN1006-2 (KiCad packages3D, STEP)
  • 3D model files: esd5431n-etched.step / esd5431n-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esd5431n.step / esd5431n.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
